New Morrisons boss David Potts has waved goodbye to five senior directors who operated under outgoing chief executive Dalton Philips, according to reports.

The management shake-up is ostensibly to “simplify and speed up” the retailer’s troubled business. During his two-week reign, Potts has already decreed that Morrisons head office staff must work in-store for one week per year, has conducted several store visits – both expected and unannounced – and abolished the retailer’s high-tech Intelligence Queue Management System.

The five departing executives will quit both the board and the company. They are group customer marketing and digital director Nick Collard, group retail director Martyn Fletcher, group property and strategy director Gordon Mowat, group logistics director Neal Austin and convenience managing director Nigel Robertson.

Two executives to retain their roles are Ross Eggleton as lead logistics and Miles Foster to lead the M local chain. Two incoming members of staff were also announced – Andy Atkinson is interim marketing director and Clare Grainger is retail director.
